From 7b49ffd99046f5dcf565c30d234a39a6b11b244c Mon Sep 17 00:00:00 2001 From: Teodor Calin Date: Wed, 27 May 2026 17:31:43 -0700 Subject: [PATCH] test: lift statement coverage from 2.5% to 91.9% Add structural tests for every adapter the runtime owns: streams (Listen, Dial, SendDatagram, Accept, full stream-adapter accessor set + Read EOF + Write error), handshake (Runtime accessors + all 13 service-adapter shims), policy (Runtime accessors + full policy-manager + runner adapter delegation), events (Publish / Subscribe happy + nil-daemon short-circuits), trust (asCoreapiTrust bridge), and lifecycle (StartPlugins / StopPlugins / dep wiring). Tests use the daemon's real PortManager + TunnelManager via the public surface (AddTunnelPeer, RegisterTrustChecker, RegisterHandshakeService, Ports().NewConnection, Listener.TrySend, ProcessRelayedApproval), so no fakes shadow the production paths. Remaining sub-100% functions (DialAndSend success path, identity-bearing PublicKey/Sign, Registry, Dial success) are ceiling-bound: each requires either a daemon constructed with a real Ed25519 identity (only settable via Start, which requires a live registry) or a successfully ESTABLISHED TCP-style handshake against a peer daemon. Neither is reachable from a single-process unit test in this package. go test -race -count=1 -timeout 180s ./... passes. --- zz_adapters_test.go | 159 ++++++++++++ zz_deps_test.go | 176 +++++++++++++ zz_eventbus_internal_test.go | 50 ++++ zz_handshake_adapter_test.go | 32 +++ zz_listener_test.go | 84 +++++++ zz_policy_manager_test.go | 201 +++++++++++++++ zz_streams_ceiling_test.go | 471 +++++++++++++++++++++++++++++++++++ zz_trust_test.go | 46 ++++ 8 files changed, 1219 insertions(+) create mode 100644 zz_adapters_test.go create mode 100644 zz_deps_test.go create mode 100644 zz_eventbus_internal_test.go create mode 100644 zz_handshake_adapter_test.go create mode 100644 zz_listener_test.go create mode 100644 zz_policy_manager_test.go create mode 100644 zz_streams_ceiling_test.go create mode 100644 zz_trust_test.go diff --git a/zz_adapters_test.go b/zz_adapters_test.go new file mode 100644 index 0000000..d6d660f --- /dev/null +++ b/zz_adapters_test.go @@ -0,0 +1,159 @@ +// SPDX-License-Identifier: AGPL-3.0-or-later + +package runtime_test + +import ( + "testing" + "time" + + "github.com/TeoSlayer/pilotprotocol/pkg/daemon" + "github.com/pilot-protocol/handshake" + "github.com/pilot-protocol/runtime" +) + +// TestHandshakeRuntime_Accessors exercises the read-only accessors on a +// HandshakeRuntime backed by a freshly-constructed daemon.
